Senior Front-end Developer (React / Next.We build complex, business-critical software — We have four front-end developers, working across two teams. Where you'd land isn't decided yet — one of those teams, or possibly a new one — but wherever it is, you'll collaborate closely with all of them. You'd be one of our senior front-end voices: not just shipping features, but shaping how we work across the board — the architecture, the standards, the quality bar, together with the rest of the front-end crew. Day to day, you'll work alongside our back-end developers (Python/Django), our product owners, and — often directly — our clients.
This is a role for someone who thinks in systems rather than components, and who cares as much about _why_ something is built a certain way as _that_ it works.
Quality comes first.* We'd rather ship a little later and get it right than ship fast and fragile. On business-critical systems, that's not a luxury — it's the job.
* *js does what it does beats knowing ten libraries shallowly.
* *When something breaks, you're curious about it, not allergic to it.
* *Small teams, short communication lines, and process that earns its place. Design and build modern React / Next.js applications that stay maintainable as they grow.
* Set front-end standards, build reusable components, and create patterns with your team
* Work closely with our back-end developers to integrate APIs and business logic cleanly.
* Own quality end to end, including in production: reading logs, tracing issues, and diagnosing incidents together with our DevOps and sysadmins rather than handing them off.
* Review code, raise the bar, and help good front-enders across our teams become even better — without slowing them down.
5+ years in front-end development, with deep, current React and TypeScript experience.
* A strong grasp of front-end architecture: component design, state management, and how structural choices affect maintainability, bundle size, and runtime performance.
* The ability to measure and improve performance (Core Web Vitals, bundle analysis, profiling) — and to understand the cost of the trade-offs you make.
* Comfort across the full lifecycle: version control, testing, debugging, CI/CD, deployment, and maintenance.
* Excellent English and the confidence to work directly with product owners and clients.
* Senior judgment: you know when to be rigorous and when to be pragmatic, you take ownership of outcomes, and you make the people around you better.
*Nice to have:* Python/Django and SQL (you'll work closely with our back-end teams), real depth in accessibility, a good design sensibility, or experience setting standards within a team.
We use AI tools in our work and we intend to be genuinely good at it — but quality is non-negotiable, and it always comes first.
We want someone whose own understanding is deep enough to use AI as an accelerator without ever outsourcing judgment to it: reviewing and directing AI-generated code as critically as you'd review a junior's pull request, catching the subtle things it gets wrong, and never shipping code you don't fully understand. You prefer to live in the IDE and would rather not talk to clients.
* You consider AI-generated code "done" when it compiles. Aanvullend pensioen
* Budget voor professionele ontwikkeling
* Werk vanuit huis
